DECK-CLEANER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 358,586, dated Mar-ch 1, 1887.

Application filed September 24. 1886. Serial No. 214,431.

To aZZ whom, it may concern:

Be it known that LWILLIAM N. WHITELEY, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio,'have invented certain new and useful Improvements in Grain-Binders-namely, a Deck-Cleaner; and I hereby declare the following to be such a full, clear, and exact description ofthe invention as will enable any person skilled in the art to which it pertains to construct and use the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates generally to that class of self-binding harvesters wherein the cut grain is carried from the grain platform up to and over the main driving-Wheel and delivered upon an inclined bindingdeck by means of an elevator composed of a canvas belt running over rollers, a second belt of similar construetion being placed above. the first to facilitate the upward flow of grain.

'My invention relates particularly to the mechanical means employed to facilitate the delivery of the grain from the elevators to the binding receptacle or deck, and is in the nature of an improvement upon the usual devices employed for that purpose.

One of the difficulties in delivering the cut grain from the elevators to the bindingdeck is that in lodged or tangled grain, instead of going up the elevator with the stalks of grain at right angles to the line of motion, it will go up endwise and,breaking over the upper edge of the binder-deck, hang in that position, as shown in Fig. 5, clogging the space between the binder-deck and the elevatorbelt to such an extent as to seriously check the flow of grain and greatly impede the effective working ofthe machine. This was sought to be prevented by the device described in my patent granted October 5, 1886, numbered 350,404, in which I have provided a reciprocating bar lying upon the binder-deck near its upper edge and having ratchetshaped teeth projecting therefrom at right angles with the deck, while upon the upper edge of the deck, or a fixed part thereof, were similarly formed teeth projecting in prolongation of the line of the deck toward the elevator belt. The difficulty experienced with this form of cleaner was (No model.)

that the series of upright teeth of the deckcleaner and of nearly horizontal teeth upon the upper edge of the binder-deck formed a sort of trough, in which the grain would collect, to the detriment of the tree and effective Working of the machine. In practice the principle upon which this deck-cleaner was constructed was found to work well, requiring only slight modifications to render its operation entirely successful. These modifications have been made and are herein described.

Instead of forming teeth upon the upper edge ofthe binding-deck, I place the reciproeating bar upon the deck at its extreme upper edge and form upon it teeth projecting toward the elevator and in the same plane as the binding-deck, thus securing as effective a cleaning device and at the same time offering no obstruction to the downward flow of the grain. The device herein described is therefore an improvement upon my former device above mentioned.

In the drawings, Figure l is a perspective view of a grain-binder having my improved deck-cleaner attached thereto. Fig. 2 is a plan view of a portion of the same, showing the relation of the declccleaner to the elevator-roller. Fig. 3 is a cross-section through the elevator-roller,deck-cleaner, 850., showing the manner of attaching the latter to the har-- vester. Fig. 4 is a perspective view of the deck-cleaner proper when detached from the surrounding parts, and Fig. 5 is aperspective view showing the position of'the clogging grain in a binderwhere no device is provided for keeping the upper edge of the binder-deck clean and clear of clogging matter.

Similar letters refer to like parts in the several views.

A is the elevator side or frame, in which is jourualed the elevator-rollers a a B is the binding-deck; b is the butt-board, Z) is the head-board; G is the knotter mechanism; 0 isthe binder-frame; D is the binder-wheel; E is the tyer-wheel; d e are the ejectors, all constructed and arranged in the usual manner.

The elevators are operated by the usual chain and sprocket-wheels. (Not shown.)

The butt-board b is movably attached to the adj usting-bracket f by the link f one end of which isjointed to said board and the other end is jointed to said adj usting-hracket. Its

position at this end is controlled by the adjusting-leverj, which may cause the bracket f to swing in or out at its other end. Its extension h is jointed to and carried around by the crank h on the end of the pinion-shaft h.

M N are the packers.

Thus far the machine is constructed in the usual manner.

Fixed to the harvester proper,by the bracket 70 at the front end and by any convenient means at the back end, is the deck-cleaner board F, the lower edge of which is beveled off and lies upon the top of the binder-deck at its upper edge, forming a continuation thereof. Upon the top of the board F is fitted the deck-cleaner G, which has formed upon it the two downwardly-projecting lugs or ears 9 and g, the lug g being perforated to take the end of the connecting-rod H, the opposite end of which is pivoted to the lever J, whose opposite end is pivoted to the bracket z fixed to the elevator-side. The connecting-rod L is also pivoted to the lever J, and its opposite end is pivoted to the butt-board extension h and the deck-cleaner therefore receives its motion through the rods H L and vibrating lever J coincidently with the butt-board. The lugs g and 9 attached to the deck-cleaner G pass through slots through the deck-cleaner board F. A pin passed through the hole in g and the hook end of the rod H through that in g secure the deck-cleaner G from rising from its place.

Formed upon the under side of the deckcleaner G is the downwardly-projecting rib or web m, the function of which is to cover the space between the deck-cleaner G and board F, thus preventing straw and other clogging matter from entering and retarding its free move ment.

Upon the upper edge of the deck-cleaner G is formed a series of teeth, mt, each composed. of a gradual incline and an abrupt nearly right-angled drop, the points of the teeth thus formed projectingtoward the butt-board, (and consequently toward the front of the machine.)

The form of the teeth is clearly shown in Fig. 2.

The board F is provided as a matter of convenience in constructing, as it in effect forms a part of the binding-deck proper, and the deck-cleanerG might as well be placed upon the deck itself as upon the board F, which is only a continuation thereof.

The operation of my invention is as follows,

viz: The harvester being in motion and the elevators bringing up tangled grain, the tendency is for it to break over the upper edge of the binder-deck and accumulate lengthwise thereon, as shown in Fig. 5, thus clogging the space between the deck and elevator-belt. While this is taking place the teeth of the deck-cleaner G engage the grain, and by its vibrating movement draw the grain by successive stages up to the toothed butt-board b, which, by its peculiar motion, (as shown by dotted lines in Fig. 2, derived from the crankshaft h,) rakes the grain down to the packers M N, which form it into a gavel in the usual manner.

Having thus described my invention, its construction, operation, and uses, and without wishing to be understood as confining my claims of invention to any precise form or proportion of parts so long as the mechanism consists, essentially, of the principles of construction and mode of operation herein described, what I claim as new, and desire to secure by Letters Patent, is-

1. In a grain-binder, the deck-cleaner consisting of a fiat bar lying upon the binderdeck at its upper edge, forming a continuation thereof, and being provided with a series of teeth formed upon the edge next to the elevator-belt and projecting toward it in the Same plane as the binder-deck, the said cleaner having imparted to ita reciprocating motion,

substantially as shown and described, in com- 'for the purpose of preventing straws and other clogging matter from entering said space and impeding the free sliding movement of the deck-cleaner.
